In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: What position did Richard Seymour play on the Patriots? Passage:Battling the Dolphins for the division lead, the Patriots erased a 13–6 gap with a Brady touchdown pass to David Givens in the third. The Dolphins marched down field late in the fourth; during this drive a Ricky Williams first down run was protested by the Patriots who felt Williams' knee touched the dirt infield at Pro Player Stadium, but the challenge was denied. The Dolphins attempted a 35-yard field goal at the two-minute warning, but the kick was blocked by Richard Seymour. The Dolphins smothered the Patriots' final drive attempt (the decisive play came when former Patriot Terrell Buckley stopped Kevin Faulk for a four-yard loss and the game went to overtime. Controversy ensued on the coin flip for overtime; referee Gerald Austin used a silver dollar; the coin came up Lady Columbia (which is "heads" on a silver dollar) but Patriot captains Brady and Seymour protested that it came up "tails." The Dolphins drove downfield but missed another 35-yard field goal try, in part because Olindo Mare couldn't plant his foot on the infield dirt, which was still in place because of the Florida Marlins' run towards their 2003 World Series victory; after forcing a Patriots punt Jay Fiedler was hit by Tedy Bruschi and lobbed a 60-yard pass picked off at the Patriots 18-yard line by Tyrone Poole. Brady then ended the game with a spectacular 82-yard touchdown strike to Troy Brown and a 19–13 final.
